Serial No. 389,175. e To all whom it may concern: Fig. 7 is afra entary plan view showing Be 1t known that I, LLEWELYN J. I Av1ns, a slightly modiii d form of'lifting lever.

a citizen ofthe United States, residing at n carrying the invention into effect, I incinnatl, in the county of Hamilton and employ a bodybar or lifting lever IOwhich State of Ohio, have invented certain new and is providedfatits forward end with a head 55 useful Improvements in Valve-Spring Lift- 11 in the rear of which is'ajslot 12. Pivoted ers, ofwhich the following is a specification. upon the head are jaws 13 provided at their 1113 invention relates to an improved lower edges with inwardly directed lateral valve spring lifter of the general character flanges 14. T ese jaws' are provided with disclosed in Patent No. 1,811,805, issued to mating ears15 overlying the head at its me July 29,1919,. and has as one of its ends. andextending through said ears and prlncipal objects to provlde a device where the head is a pivot pin 16 swingingly conin the operation of lifting a valve spring may nectlng the jaws with the head. Projecting be speedily accomplished. rearwardly from the jaws' are lugs 17 and 15 The invention hasas a further object to slidable withinthe slot 12 to engage between i provide avalve spring lifter employing a these lugs a wedge'block 18f Tlhreaded rigid fulcrum bar for the lifting lever of through the block is an adjusting'screw 19" the device and wherein] said her will be journaled atgit's inner end in the inner end formed to support the lever either close to Wall of said slot and fixed to the screw. is
